Read on for adjustment instructions. - Has worked perfectly from the start. The more expensive one I fitted was very erratic, possibly due to my dodgy re-wiring of the alternator. This one was not so fussy and gave a steady reading, albeit inaccurate. To calibrate it, I adjusted the display using the button on the back. Press and hold and it will increase the reading. Release, press and hold and the reading will decrease. I have left this review 2 years after purchase because I changed my alternator and could not remember how to change the readout. YouTube got me close enough to work it out.

Leider lassen sich die Betriebsstunden nicht vom alten Instrument durch Einstellung übernehmen.
